SPECIFICATiON forming part of Letters Patent No. 781,771, dated February'7, 1905.

Application filed April 21, 1904:. Serial No. 204,268.

To 117/ [I'll/mt it may concern..-

Be it known that .1, TVILLIAM H. Gaanxna, Jr.. a citizen of the UnitedStates, residing at Park City, in the county of Summit and State ofUtah, have invented certain new and useful Improvements in Planes; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in planes, and particularly tothe class of rabbet iug-planes.

The object of the invention is to provide a plane of this characterhaving means whereby the handle may be adjusted to one side to permitthe plane to be used close up against a shoulder without danger ofstriking the knuckles of the operator.

Another object is to provide means whereby the plane is prevented frombecoming clogged with shavings.

\Yith this and other objects in view the invention consists of certainnovel features of construction. combination, and arrangement of parts,as will be more fully described, and particularly pointed out in theappended claims.

In the accompanying drawings. Figure l is a longitudinal verticalsectional view of a plane embodying the invention. Fig. 2 is a verticalcross-section on the line .2 2 of Fig. i. Fig. 3 is a similar view onthe line 3 3 of Fig. 1. Fig. -l is an enlarged fragmentary view of theplane-tree. the inner end of the handleplate. and the device for lockingthe handle in its adjusted positions.

Referring more particularly to the drawings, ldenotes a rabbeting-planoconsisting of a bottom or base plate 2 and side flanges 3. Between saidflanges is arranged the bit-support l, on which is secured the plane-bit5 and adjusting mechanism 6, by which said bit is regulated. These partsmay be of the usual or any suitable construction.

On the forward end of the plate 2 is arranged the usual hand-knob orgripT. On

the rear end of the plate 2 is formed two upwaidly-pro ecting lugs 8 and9, in which are formed horizontal longitudinally disposed apertures 10.Between the lugs 8 and 9 is arranged a narrow handle plate or bar 152,the lower side of which is curved or rounded in cross-section, as shownat 13. On the ends of the bar 12 are formed upwardlyprojecting ears orlugs it and 15. On the forward lug it is formed a forwardly-projectingstud or trunnion 16, which is adapted to pivotally engage the aperturein the forward lug 8, formed on the base-plate of the plane-tree.

On the upper edge of the lug ii is formed a series of radial notches 1T.prefcratdythree in number, arranged as shown in Fig. 3 of the drawings.in the upper end of the lug 8 is formed a recess or slot lb, in which ispivotally mounted a pawl or dog It), which is adapted to be engaged withone or the other of the notches 17 in the lug ii. A coiled spring 21) ismounted in a recess in the lug 8 and is adapted to bear under thelorwardend of the pawl or dog it) to hold the same in engagement withthe notches 17. On the pawl or dog it) is secured a laterally-projectingfinger-piece 2i, by which the pawl may be disengaged from said notches.

The lug on the rear end of the plate or bar 12 is provided with athreaded aperture 22, into which is screwed the end of a pivotscrew 23,which passes through the aperture 10 of the lug 9. thereby pivoting thisend of the handle to the plane-tree, thus permitting the handle to beswung laterally in either direction and locked in place. This radial orlateral :uljustmcnt of the handle permits the plane to be used close upagainst the shoulders formed by the rabbeting of a board withoutdangerol' injuringthe knuckles of the operator. I

It has been found in practice that planes of this character frequentlychoke up with shavings, due to the width of the shaving being sometimesgreater than the width of the space between the side flanges of theplane, so that the shaving binds and does not pass out. in order toovercome this ditliculty, .l have devised a means for splittii'ig theshavings, said means consisting of a vertically-disposed knife or cutter2%. the lower end of which is rounded and beveled to a thin sharp edgeand is l adapted to project through a slot 25, 'forinet in the lowerplate or base 2 of the plane-tree.

, material in which a clean square edge is desirof the lug 27 isarranged a clamping-lever 30.

In order to adjustably hold the knife 2 in place in said slot, aclamping-bolt 26 is provided. Said bolt is mounted in a lug 27, whichprojects upwardly from the plate 2. The forward side of the lug has abeveled or cam face 28, while the rear face of the same is perpendicularor square. In the rear end of the bolt is formed a vertically -disposedslot '29, in which the knife 24 is disposed.

On the forward end of the bolt 26 between the head of the same and thebeveled face 28 Qn the inner end of said lever is formed a head 31,having a beveled ,or cam face 32, which is adapted to engage the beveledface 28 of the lug 27, so that when said lever is turned to the rightthe bolt 26 will be drawn forwardly, thereby clamping the blade of theknife tightly against the perpendicular side of the lug 27, in whichposition it will be firmly held until released by turning the lever 30to the left. By this means the knifeblade may be adjusted to project itscutting end to the desired distance below the baseplate of theplane-tree and then clamped in this position, thus enabling slits ofvarious depths to be cut. in planing, the knife 24 is adjusted toproject about the same distance as the plane-bit, so that a slit isformed in the wood in advance of the plane, thereby causing the shavingto split, which prevents the same from wedging in the throat of theplane.

WVhile the primary object of the cutting blade or knife 24 is to splitshavings, the same has been found useful for other purposes,such as forcutting veneers, leather, and other thin able.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention. 1

Having thus described my invention, what 1 claim as new, and desire tosecure by Letters Patent, is

1. In aplane,the combination with the plane tree or stock, of a handlesecured at its lower end to a plate or bar, apertured lugs or earsformed on the base-plate of said plane-tree, lugs formed on the ends ofsaid handle plate or bar, a stud formed on the forward lug of said plateor bar and adapted to engage the aperture of the forward lug of saidbaseplate, a threaded aperture formed in the rear lug of saidhandle-plate to receive a pivotbolt which is engaged with the aperturein the rear lug of said base-plate, whereby said handle-plate and handleis pivoted to said base-plate to swing laterally to one side or theother, and apawl for holding said handle in an upright or laterally-adjusted position, substantially as described.

2. In a plane,the combination with the plane tree or stock, of a handlesecured at its lower end to a plate or bar having a rounded undersurface, apertured lugs or ears formed on the base-plate of saidplane-tree, lugs on the ends of said handle plate or bar, a stud formedon the forward lug of said plate or bar, and adapted to engage theaperture of the forward lug of said base-plate, a threaded apertureformed in the rear lug of said handleplate to receive a pivot-bolt whichis engaged with the aperture in the rear lug of said baseplate, wherebysaid handle-plate and handle is pivoted to said base-plate to swinglaterally to one side or the other, notches formed in the upper edge ofthe forward lug of said handle-plate and a spring-pawl pivotallyconnected to the adjacent lug of said plane-tree to engage one or theother of said notches and thereby hold said handle in an upright,orlaterally-adjusted position, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing wit- DEBSSBS.
